In my hopes of "new" ideas that future waves could bring, I am hoping for all kinda of new and fun things. Rebels ships with strong, Front arcs. Imperial ships with broadside abilities, A-symmetrical firing arcs for a ship perhaps?
But what if a ship had a stronger REAR arc. The idea being that it wants to fly past you and get you best after it's passed you by. I don't know if there is any ship that conforms to that in the Star Wars universe, but the idea itself could be somewhat cool. A ship you certainly would never want to chase. It would fly way differently.
